RFID Stain Tracking for Precise Fabric Pretreatment and Laundering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fabric items often get forgotten or misplaced in a pile of laundry, leading to untreated stains during washing, resulting in potential damage due to improper cleaning cycles and lack of chemical pretreatment.
Innovation Solution
A system using RFID tags attached to stained areas of fabric items, which can be activated to emit signals for location and communicate stain information to laundry equipment, ensuring precise treatment and optimal cleaning parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If fabric items are accumulated in a laundry hamper for later washing, then convenience of laundry management is improved, but stain location and item identification are lost
Solution Approach 1:
The system applies stains markers to fabric items at the moment of staining, performing the marking action immediately before the item is placed in the laundry hamper. This preliminary action ensures stain location information is captured and preserved throughout the accumulation period, resolving the contradiction between convenient laundry management and information retention.
Solution Approach 2:
The patent introduces stains markers as an intermediary element that bridges the fabric item and the laundry management system. These markers carry identification and location information, enabling the system to track stained items throughout the laundry process without requiring constant user attention or manual tracking.
2Device complexity
If stained items are sorted for washing without tracking system, then sorting process is simple, but stains may be missed and fabric items may be ruined
Solution Approach 1:
The stains markers enable the fabric items to essentially identify themselves during the sorting process. When a user scans or detects the markers, the system automatically provides stain location and treatment information, making the sorting process reliable without requiring complex user knowledge or manual inspection of each item.
Solution Approach 2:
The system provides feedback to the user about which items are stained and where, through the markers that communicate stain information. This feedback mechanism ensures that no stains are missed during sorting, while keeping the interface simple and the overall process manageable.
3Reliability
If chemical pretreatment is applied to all fabric items, then stain removal effectiveness is improved, but fabric damage risk increases and resource consumption rises
Solution Approach 1:
The system enables targeted application of chemical pretreatment only to the specific stained areas identified by the markers, rather than treating the entire fabric item uniformly. This localised approach maintains stain removal effectiveness while reducing unnecessary chemical exposure to non-stained areas, thereby minimizing fabric damage risk and resource consumption.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables effective sorting and precise treatment of stains before laundry, preventing damage and ensuring optimal stain removal by allowing users to locate and treat stains accurately and transmit relevant information to laundry machines.
Implementation Method 1
The transceiver device can be used to locate the stain on the fabric item by activating an RFID tag
Data Source
AI summary
A system and method for tracking, treating, and laundering stains on a fabric item is disclosed. The system and method uses a stain tracking app to store and transmit data about the stain to a piece of laundry equipment. The system and method optionally uses an RFID tag to mark the stain or stains on a fabric item and uses a transponder or smartphone to locate the RFID tag and the stained fabric item. The user is then able to precisely locate both the stained fabric item and the precise location of the stain or stains on the fabric item for an optional chemical pretreatment prior to laundering. The stain tracking application transmits information about the stain to the piece of laundry equipment which can then be used to determine optimal pre-treatment and cleaning parameters to optimize removal of the stain or stains.
